Does Jupiter rotate differential?
Abstract. Jupiter's atmosphere is rotating differentially, with zones and belts rotating at speeds that differ by up to 100 metres per second. Whether this is also true of the gas giant's interior has been unknown1,2, limiting our ability to probe the structure and composition of the planet3,4.
What is differential rotation quizlet?
Differential rotation. The tendency for a gaseous sphere, such as a jovian planet of the Sun, to rotate at a different rate at the equator than at the poles. More generally, a condition where the angular speed varies with location within an object. Great Red Spot.
What is the Jupiter rotation?
Like the rest of the gas giants, Jupiter has a ring, albeit small and flat. Its rotation is the fastest of all solar system planets, rotating once on its axis every 10 hours. This means at the equator, Jupiter is moving at 22,000 mph, compared with 1,000 mph for the Earth.
What is the rotation of Jupiter from the Sun?
Orbit and Rotation One day on Jupiter takes only about 10 hours (the time it takes for Jupiter to rotate or spin around once), and Jupiter makes a complete orbit around the Sun (a year in Jovian time) in about 12 Earth years (4,333 Earth days).
What is differential rotation in astronomy?
Differential rotation is seen when different parts of a rotating object move with different angular velocities (rates of rotation) at different latitudes and/or depths of the body and/or in time. This indicates that the object is not solid. In fluid objects, such as accretion disks, this leads to shearing.
What causes differential rotation?
Differential rotation is caused by convection in stars. The movement of mass is due to steep temperature gradients from the core outwards.
What is differential rotation astronomy definition?
Differential rotation is seen when different parts of a rotating object move with different angular velocities (rates of rotation) at different latitudes and/or depths of the body and/or in time. This indicates that the object is not solid. In fluid objects, such as accretion disks, this leads to shearing.
What is differential rotation of the Sun?
However, unlike Earth which rotates at all latitudes every 24 hours, the Sun rotates every 25 days at the equator and takes progressively longer to rotate at higher latitudes, up to 35 days at the poles. This is known as differential rotation. The Sun rotates in the same direction as Earth.
Why does Jupiter rotate?
When Jupiter formed, it accreted its atmosphere (over 95% of the planet's total mass!) from the hydrogen and helium gas in the protoplanetary disk surrounding our Sun. As Jupiter ate up this gas mass, it must have begun to spin faster as it also ate up the gas's angular momentum.
How many rotations does Jupiter make?
Next to each planet's name, we have listed the time it takes for each planet to make one full rotation as well as the speed each planet moves at its equator. Jupiter, for example, makes one rotation in 9h 55m but moves 27 times faster than Earth at its equator, spinning at a whopping 45,583 km/h!
What causes differential rotation of Jupiter?
The polar radius of Jupiter is 66,800 km, while the equatorial radius is 71,500 km. In other words, points along Jupiter's equator are actually 4,700 km more distant from the planet's center. Jupiter is a ball of gas, and so it actually experiences differential rotation.
How do you determine differential rotation?
There are many ways to measure and calculate differential rotation in stars to see if different latitudes have different angular velocities. The most obvious is tracking spots on the stellar surface. By doing helioseismological measurements of solar "p-modes" it is possible to deduce the differential rotation.
What is the meaning of differential rotation?
In a rotating solid body, regions that are adjacent at one point in time will remain adjacent as the body rotates. This means that points further from the rotation centre will travel at greater speeds than those closer in.
What is meant by differential rotation?
In a rotating solid body, regions that are adjacent at one point in time will remain adjacent as the body rotates. This means that points further from the rotation centre will travel at greater speeds than those closer in.
How is Jupiter’s rotation measured?
Unlike Mars or Mercury, Jupiter has no surface features that you track to measure the rotation speed; there are no craters or mountains that rotate into view after a specific amount of time. Jupiter has the fastest rotation of all the planets in the Solar System.
What is interesting about Jupiter’s rotation period?
What is interesting about Jupiter's rotation period? It is the fastest in the solar system.
